Networking
Switching between USB, Ethernet, and wireless connections (Macintosh only)

topics on troubleshooting specific connection types if you encounter difficulties during configuration.
Note: The printer supports one active local connection (USB) and one active network connection (Ethernet or
wireless) at a time. It is not possible to connect to both Ethernet and wireless at the same time.
